I tried this out today, and the results were mixed. Here's the lspci
output for this card:

00:0f.0 SCSI storage controller: QLogic Corp. ISP1020 Fast-wide SCSI
(rev 05)

When I built a patched driver and plugged it in, here's what I saw in
dmesg:

qla1280: no version magic, tainting kernel.
qla1280: QLA1040 found on PCI bus 0, dev 15
scsi(0:0): Resetting SCSI BUS
scsi0 : QLogic QLA1040 PCI to SCSI Host Adapter
       Firmware version:  7.65.00, Driver version 3.25
  Vendor: Quantum   Model: DLT4000           Rev: CD3C
  Type:   Sequential-Access                  ANSI SCSI revision: 02
scsi(0:0:2:0): Sync: period 10, offset 12
st: Version 20040213, fixed bufsize 32768, s/g segs 256
Attached scsi tape st0 at scsi0, channel 0, id 2, lun 0
st0: try direct i/o: yes, max page reachable by HBA 1048575

Looked pretty good, other than it seems to think that my card is a 1040
and not a 1020. I then tried to do some operations with my tape drive:

jtlayton@salusa:/usr/src/linux-2.6.4% sudo mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (1010000):
 ONLINE IM_REP_EN

I then tried to use tar to write a file to the tape and it failed almost
immediately:

jtlayton@salusa:~% sudo tar cvf /dev/nst0 ./wolf-linux-1.33.x86.run
./wolf-linux-1.33.x86.run
tar: /dev/nst0: Wrote only 0 of 10240 bytes
tar: Error is not recoverable: exiting now

These errors seem to cause these messages to pop up in dmesg:

st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).

Please let me know if there's any info I can provide that might help, or
if you need me to test another patch.

Heck, I'll even offer up a case of beer (or an equivalent reward) if we
can get it working!

Thanks,
